HYDROCARBON-LAM P.

SPECIFICATION forming part of Letters Patent No. 735,682, dated August 4, 1903.

Application filed June 28, 1901.

To all whom it may concern:

Be it known that I, RUSSELL THAYER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Hydrocarbon- Lamps, of which the following is a specification.

At present the only way of removing the Waste oil that escapes from the vaporizer, burner, and other sources and which accumulates in the bottom of the globe that surrounds the burner and mantle is to unfasten the globe and permit it to swing downward until the oil can be drained out into a suitable re ceptacle or onto the ground. In addition to the inconvenience of removing this waste oil much danger is caused by its presence in an inclosed space free from atmospheric air, for

the reason that the intense heat from the burner causes this waste oil to ignite.

It is the object of the present invention to overcome the above-recited disadvantageous features, and to this end suitable means for detachably engaging the lower portion of the hydrocarbon-lamp is provided, whereby the waste oil may be accumulated and removed 'without disturbing the lamp-proper.

A further object is to so arrange these means that an air-space is provided at the lower portion of the lamp, whereby atmospheric air is allowed to pass up through the globe, thus eliminating all danger of ignition of the waste oil.

The nature, characteristic features, and scope of the invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, and in which- Figure 1 is an elevational view illustrating the invention, and Fig. 2 is a sectional view of the lower po'rtion of Fig. 1.

In the drawings, a is a hydrocarbon incandescent lamp which is equipped with the usual dome, burner, incandescent mantles, and globe. As shown, the globe b is hinged,

as at b, and is provided with a spring-catch Serial No. 66,360. (No model.)

b Suspended beneath the globe bis a receptacle or bowl 0, preferably made of glass or other transparent material, which is arranged in such a manner that any oil that may leak from the vaporizer, burner, or other portion of the lamp may drip into this receptacle. To accomplish this, the globe b is provided with an opening in the lower portion of the same. beneath the globe in the following manner: Around the exterior of the globe a wire-netting is usually employed to protect it from accidental breakage. In the present invention this netting is made to carry a ring d, from which the receptacle 0 is suspended. This receptacle is loosely mounted in a second ringe, which is provided with a hinge f and catch 9, which secure the receptacle or bowl in proper position and readily permit of its being removed and replaced when occasion demands. In order to accomplish this, it is merely necessary to press the spring-catch and permit the ring 6 to swing backward, the receptacle being held in the hand meanwhile. The receptacle may be removed and the oil poured out and the receptacle replaced and returned to its original position. Between the bottom of the globe and the upper portion of the receptacle'or bowl a suitable space is provided and is shown by spacing apart the rings (1 and e, whereby air may pass into the interior of the globe. This isimportantin orderthat the intense heat from the burner may not ignite the waste oil in the bowl 0. Obviously such an arrangement is simple in structure and inexpensive in manufacture. By making the receptacle of glass or similar material it is readily discerned when wasteoil'has accumulated therein, and, further, the receptacle may be removed, the waste oil poured out,'and the receptacle replaced in an expeditious and convenient manner.

It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details without departing from the spirit thereof. Hence I do not limit myself to the precise construction and arrangement of parts hereinabove set forth and illustrated in the accompanying drawings; but,

Having thus described the nature and objects of the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A hydrocarbon-lamp provided with a globe having an opening at its base, a ring pivotally supported beneath the opening, and a bowl seated in said ring and arranged so as to be readily removable therefrom when the ring is tilted, the arrangement being such that in the normal position of the bowl an annular air-space is provided between its top and the base of the globe to permit free access of air to the interior of the globe, substantially as specified.

2. A hydrocarbon-lamp provided with a globe having an opening at its base, a wirenetting enveloping the globe, a ring carried 20 signed my name.
